Once it's properly mounted and calibrated it will send data once every hour or so to preserve the battery, but now it takes measurements every few minutes. Once in a while the distance drops by some thirty centimetres, I wonder if this is the cause.

Can you see the distance sensor that will, once properly mounted, measure the depth of water in a ditch on our border, in the of ? I hope potential thieves won't see it either.

Padło pytanie gdzie jest gateway. Odpowiedziałem, że Barbie jest wystawiona z mauzera. I wszystko jasne dla wszystkich, dla których ma być jasne.

Even further away from the gateways, RSSI -73, SNR 14. There will be no problem with measuring the level of water in a ditch nearby. Those sensors work pretty well at first glance, but they were not made for wild areas – still haven't found a way to switch off the very bright LEDs that light up during transmission. We want to kep this place dark at night. And the LEDs use up the battery.

The barrel was easy – just a few metres away from both the sensors. The question was how would the sensors transmit through thick, wet vegetation. I'm not measuring anything but radio parameters from this spot on the edge of a meadow in .

New sensors arrived a few days ago, but I had to wait till today with testing. Bad news – something is wrong with one of the gateways. Good news – the sensors work. Fortunately there was a short shower so I could see the sensor on the barrel at work.

I'll have to find out how many generations of storks worked on this nest, the largest I've seen in this area. Someone will have to climb that pole to take samples for radiocarbon dating.

An important day – ministers of the European Parliament approved . As usual, Poland voted against it, along with Hungary, Italy, the Netherlands, Finland, and Sweden. The Austrian minister voted for – and she is now facing serious troubles at home for her brave move. Maybe there's still a chance for our disappearing .

Didn't expect them so soon. Have to get the frying pan ready.

Had to wait a moment with an ill dog at the vet's in a nearby town – he had an urgent case.

Wild black cherry (Prunus serotina) fruit are starting to appear. The rest of the picture is completely out of focus.
